The 36-bit word width accommodates 32 data bits plus 4 parity bits per word, which maps directly to systems that need byte-level ECC or a sideband control bus without multiplexing. With a 15 ns access time, the part supports bus speeds where the memory controller must latch data within a single 66 MHz clock cycle. The write cycle time is also 15 ns, matching the read access so the bus timing is symmetrical — no extra wait states on writes. ## 172-ball FBGA — rework and layout realities This limits the part to indoor, climate-controlled environments — not suitable for extended industrial or automotive ambient without active cooling. There is no separate Vddq for the I/O — the core and output buffers share the same supply, so the decoupling plan needs a low-ESR 3.3 V rail with bulk capacitance near the BGA's centre balls. For existing BOM lines, the supply route is independent distribution and surplus inventory, confirmed lot by lot at RFQ. The base product number is CY7C057, which covers the 32K x 36 dual-port family. If a design is still in development, consider whether a currently active dual-port SRAM in a compatible package and speed grade is a better long-term choice — the 15 ns speed and 36-bit width narrow the field of drop-in alternatives.","metaTitle":"Infineon CY7C057V-15BBXC 1.152Mbit Dual-Port SRAM, 15 ns","metaDescription":"CY7C057V-15BBXC from Infineon — 1.152Mbit dual-port async SRAM, 32K x 36, 15 ns access, 172-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"15 ns","Memory Size":"1.152Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"172-LBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C057","Memory Organization":"32K x 36","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"172-FBGA (15x15)","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"How can I order CY7C057V-15BBXC or check availability?","answer":"The CY7C057V-15BBXC is obsolete and sourced through independent distribution."},{"question":"What does the 32K x 36 organization mean for system design?","answer":"The memory is arranged as 32,768 words of 36 bits each.
